Device Manager Non-Present Devices

To show non-present devices in Device Manager, do the following:

  • Open a command prompt by typing cmd in a run box.
  • At the command line, type the following: set devmgr_show_nonpresent_devices=1
  • Hit enter, then type: devmgmt.msc
  • Once Device Manager opens, click on View, then Show hidden devices

This is a great way to delete a corrupt driver that keeps re-installing itself. Just be careful not to delete something you need!
